Coke is a better fuel than coal because; -Coke produces more heat on burning than coal. … When equal masses of coke and coal are burnt, coke produces more heat. -When coke is burnt smoke is not obtained.
Which is a better fuel − coal or coke Why?
Coke is a better fuel because coke produces more heat on burning as compared to coal. Coke has higher calorific value than coal. When equal masses of coke and coal are bunt, coke produces more heat. Also when coke is burnt, smoke is not obtained whereas coal produces smoke on coal.
How is Coke different from coal?
What is the difference between coal and coke fuel? Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner.
Why do we turn coal into coke?
Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. … This process results in a hard porous material – coke.
Which fuel is the cleanest?
Which type of coal has the most energy?
Why Coke is not used as fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
Is Coke a clean fuel?
Coke is used as a fuel and as a reducing agent in smelting iron ore in a blast furnace. The carbon monoxide produced by its combustion reduces iron oxide (hematite) to the iron product. Although coke is more expensive than coal, it can be used in households as a clean fuel, relatively free of smoke and impurities.
What are the advantages of coke over coal?
(i) Coke produces more heat than an equal mass of coal. (ii) It produces ni smoke on burning and leaves no residue and as such does not cause air pollution. (iii) It is used as a reducing agent in the extraction of metals from their ores.
What is Coke made from?
When launched, Coca-Cola’s two key ingredients were cocaine and caffeine. The cocaine was derived from the coca leaf and the caffeine from kola nut (also spelled “cola nut” at the time), leading to the name Coca-Cola.
What does coke mean?
Can we make steel without coal?
The key message is this: it is possible to create low-emissions steel, without metallurgical coal. … Not to mention what products we can produce from the steel – adding value in many more ways than just exporting ore – and taking advantage of an increasing consumer demand for low carbon products.
What is the dirtiest fuel?
For the first time, energy companies in the United States are working to commercially develop the dirtiest of dirty fuels – oil shale and tar sands.
Which fuel does not cause pollution?
Hydrogen fuel cell vehicles
Hydrogen-fueled vehicles emit virtually no hydrocarbons, particulates, carbon dioxide, or carbon monoxide.
Is gas cleaner than oil?
Natural Gas Generates Fewer Harmful Emissions
Fossil fuels produce emissions that impact the environment when they’re burned. … Natural gas also produces less sulfur dioxide and nitrogen oxide than oil, making it an even cleaner choice for the air.
